It is well known how draft means, such as, yieldable by leading the rope ranged in different planes. constructions, the repeated relaxing of the spring to make a flexible for instance, a rope over several spring connected points of suspension ar- In the prior tensioning and device will cause a December 20, 1927.

In the present embodiment of the invention, a single length of metal, such as spring wire, is shaped to form a coil or which acts 50 as a spring, the same having an integral loop or eye 6 through which a rope projects, and the material is further shaped to form the arms 0 having the integral coils 10 certain displacement of the rope relative to (Z forming eyes through which the rope e 55 the points of guidance which causes fricis threaded.

Attempts have been made to obviate the device and the relatively rigid charthis drawback by the use ofrollers at these points, but their axles must be greased, and the construction is complicated and thus expensive.

It is an ob ect of H vide means for maintaining t or rope in certain position during draft and to permit yielding upon th velopment of abnormal conditions where absorption of shock is desired, as,

spring wire. With the foregoing and other objects detail, refhad to the accompanying acter of the device will be relied upon to maintain the rope in its angularly disposed position during normal operation, but will permit it to move as the device yields in order that the rope may assume ifferent angles with relation to that which is illustrated, according tothe draft or force employed in the draft rigging.

' from an inspection of the drawa normal e deft is seen for ining that the device can be made inexpensiveobstruc- 1y, since it comprises ut a single piece of *ationary metal and, notwithstanding its simplicity 7 and inexpensive structure, it has been found efficient and satisfactory in use.

I claim: 1. A tensioning device for cordage comprising a resilient structure shaped to provide two alined coils forming eyes whic are on the same plane and an intermediate eye on a different plane said eye being located between coils, theseveral eyes being resiliently connected by angularly arms.

2. A tensioning the simplest 7 device for cordage comprising a resilient bar which is shaped to rovide a centrally located eye through whicha rope may be threaded, resilient s5 coils on opposite sides of said eye and pofter drawings forming part of this application, sitioned at right angles thereto, a pair .0 wherein like characters denote correspon diverging arms which converge from the ing parts in the several views, and in outer ends of the coils the same being shaped 45 whichto provide at the junction of each pair of 9c disposed so side arms eyes which are normally in the same plane as the eye between the resilient coils.

3. In a 'tensioning device, a spring wire or rod which is shaped to provide diverging side members with eyes for the passage t erethrough of a rope to maintain the rope in V-shaped formation, wire also being bent to provide coils and an eye located between and at right angles with coils, also to provide a pair of arms which extend from the coils, each of t1e arms converging provide eyes which In testimony whereof I afliX my signature.
